I can only assume this was some attempt to slow down scroll speed (The normal freeware version scrolls like a cheetah on crack even on slowest speed setting).
When I scroll with this version of the game, which apparently is the freeware with "extras", the whole game is unplayable because scrolling itself makes the game slow to a crawl. What's more I noticed games in general were lagging afterwards so something was eating up my computer resources. A simple restart fixed that, but whatever those "extras" are shouldn't be affecting my comp outside of the game.
Meanwhile, is there any fix/workaround for either this or the standard EA freeware version? EA really should have let us play with ini files with this or something. I heard there was some config file for TD (Tiberiem Dawn, aka: the first C&C) involving reducing rendering or something but I'm not sure if that's possible here. Would using dosbox work? I can make do without online play since I'm playing more for the single player.
Oh, also the mouse cursor was flickering on and off in this version, which kind of makes the game unplayable as well because it's such a distraction and an eyesore.
